The Dutch rapid-prototyping outfit Freedom of creation(FOC) has added wood to its suite of 3-D printing materials. It isn’t wood resembling, but it’s sawdust that, when mixed with a “binder” (basically glue), forms something approximating the look of real wood and the strength of MDF, but naturally the complexity of the geometries that is able to produce is on a totally different level than compared to simple pressed wood. FOC can only print in teak and mahogany. Garrett explains: “Balsa and other light wood types have not been possible yet, because they are so light that spreading equal layers is still a problem. We are currently working on improving this with using different types of re-coaters.”
